It is built for PleasureCraft Ford Small Block V8 engines in the 302 and 351 CID range. The kit includes one Sierra 18-0677-1 exhaust elbow gasket along with the mounting hardware needed to complete the installation, so you are not left sourcing separate fasteners or gaskets to finish the job.\u003c\/p\u003e\u003cp\u003eThis kit is a companion part to the 18-1899 riser rather than a standalone riser or manifold, so it should be paired with that riser (or an existing riser of the same type) during installation. Sierra manufactures its exhaust components to meet or exceed the specifications of the original equipment parts they replace, giving boat owners a reliable way to reseal and remount their exhaust elbow without waiting on OEM lead times.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Sierra\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 18-8504\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Exhaust Elbow Mounting Kit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes:\u003c\/strong\u003e 18-0677-1 Exhaust Elbow Gasket and mounting hardware\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUsed With:\u003c\/strong\u003e 18-1899 Riser (3 inch outlet)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEngine Fitment:\u003c\/strong\u003e PleasureCraft Ford Small Block V8 (302 and 351 CID) engines\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterchangeable With:\u003c\/strong\u003e Mallory 9-40871, Osco 29001-MK\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Machined\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.24 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Dimensions:\u003c\/strong\u003e 0.39 x 0.39 x 0.39 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 808282127022\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003ePleasureCraft Ford Small Block V8 (302 and 351 CID) engines\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eMallory 9-40871\u003c\/li\u003e\n\u003cli\u003eOsco 29001-MK\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat is included in the Sierra 18-8504 kit?\u003c\/strong\u003e The 18-8504 kit includes one Sierra 18-0677-1 exhaust elbow gasket plus the mounting hardware needed to install the exhaust elbow, so no separate gasket or fastener purchase is required.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat engines does the 18-8504 mounting kit fit?\u003c\/strong\u003e This kit is designed for PleasureCraft Ford Small Block V8 engines in the 302 and 351 CID displacement range.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhich riser does the 18-8504 mounting kit go with?\u003c\/strong\u003e The 18-8504 kit is used with Sierra's 18-1899 riser, which has a 3 inch outlet.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-8504 interchangeable with other brands?\u003c\/strong\u003e Yes, the 18-8504 mounting kit is interchangeable with Mallory 9-40871 and Osco 29001-MK.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat does the 18-8504 kit weigh?\u003c\/strong\u003e The Sierra 18-8504 Exhaust Elbow Mounting Kit weighs 0.24 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the dimensions of the 18-8504 kit?\u003c\/strong\u003e The kit measures 0.39 x 0.39 x 0.39 inches.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat finish does the 18-8504 hardware have?\u003c\/strong\u003e The mounting hardware in the 18-8504 kit has a machined finish.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 18-8504 kit include a manifold?\u003c\/strong\u003e No, the 18-8504 is a mounting kit for the 18-1899 riser; it does not include an exhaust manifold.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Sierra 18-8504 gasket the same as a genuine OEM gasket?\u003c\/strong\u003e Sierra manufactures the 18-0677-1 gasket included in the 18-8504 kit to meet or exceed the specifications of the original equipment part it replaces.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan the 18-8504 kit be used to reseal an existing riser installation?\u003c\/strong\u003e Yes, since it supplies the elbow gasket and mounting hardware for the 18-1899 riser, the 18-8504 kit can be used when remounting or resealing that riser on PleasureCraft Ford Small Block V8 302\/351 CID engines.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the UPC for the Sierra 18-8504 kit?\u003c\/strong\u003e The Sierra 18-8504 Exhaust Elbow Mounting Kit has UPC 808282127022.\u003c\/p\u003e","brand":"Sierra","offers":[{"title":"Default Title","offer_id":48988434268379,"sku":"SIE-18-8504","price":14.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/SIE-18-8504_lg__62816.1558133130.500.750.jpg?v=1785188555","url":"https:\/\/www.goodvibesmarina.com\/products\/exhaust-elbow-mounting-kit-18-8504-for-pleasurecraft-ford-small-block-v8-302-351-fits-18-1899-riser-replaces-osco-29001-mk-mallory-9-40871","provider":"Good Vibes Marina","version":"1.0","type":"link"}
